Heidelberger Chlorella Magnesium as Magnesium Citrate Powder – 140 g
140 g · 7.4160 g per day
Product description
The magnesium citrate powder is a very high-dose single-ingredient product providing 593 mg of magnesium per daily dose. Although the powder form allows flexible handling, the manufacturer’s target amount is well above typical supplemental intakes. From an orthomolecular perspective, the key issue is therefore less the complexity of the product and more the dosing question.

Product character
The magnesium citrate powder is a very high-dose single-ingredient product providing 593 mg of magnesium per daily dose. Although the powder form allows flexible handling, the manufacturer’s target amount is well above typical supplemental intakes. From an orthomolecular perspective, the key issue is therefore less the complexity of the product and more the dosing question. Total intake, individual tolerance and additional magnesium sources should be considered particularly carefully at this level.

Physiological functions, notes on high or insufficient intake and relevant interactions — presented separately from the specific product assessment.
Magnesium
Magnesium is an essential mineral involved in numerous enzymatic reactions. For product assessment, the manufacturer’s dosage, active-ingredient forms and reference values are considered separately.
Functions
Magnesium contributes, among other things, to normal muscle and nerve function and to normal energy-yielding metabolic processes. It is also involved in processes related to protein, bone and DNA.
Possible signs of insufficient intake
Insufficient magnesium intake can present with nonspecific symptoms; possible indications may include neuromuscular complaints. Individual symptoms do not establish a diagnosis and should not be assessed in isolation.
Points to consider at high intake
High amounts from supplements can mainly cause gastrointestinal symptoms such as diarrhoea, nausea and abdominal cramps. With severely impaired kidney function, the risk of magnesium accumulation increases; high doses should then be medically assessed.
Special considerations
With impaired kidney function, magnesium excretion is reduced. Product dose, magnesium form, tolerance and total intake should therefore be considered separately.
Interactions / caution
Magnesium can affect the absorption of certain medicines, including some antibiotics and bisphosphonates. Timing intervals and individual medication should be reviewed with regular use.
Scientific assessment
Studies, meta-analyses and randomized controlled trials on the active ingredient – explained clearly and linked to sources.
